Abstract
Heusler-like alloy Fe2CrAl was prepared and studied. Structure determination was done by X-ray. The structure was found to conform to the B2 type. Magnetic hyperfine fields in this sample were studied by the Mossbauer effect. The Mossbauer spectra were recorded over a range of temperature from 40 to 296 K. The Mossbauer spectra showed the co-existence of a paramagnetic part with a magnetic hyperfine portion at all recorded temperatures. Even with the distribution in the magnetic hyperfine field, the average hyperfine field follows the (T/T c)3/2 law. The paramagnetic part of the hyperfine field is explained in terms of the clustering of Cr atoms.
